Reflections on the design of a CAI operating system

Abstract

A time shared general purpose computer programmed to operate in conversational mode may be used as a vehicle for computer aided instruction (CAI). Although at present CAI is a relatively expensive medium the outlook is that as the efficiency of time sharing system increases, the cost per terminal of such a CAI system will decrease and CAI will become practical for more and more educational applications. As a result R&D activity in CAI has increased markedly in the last few years.
